22 year old boy looking for a flat share in barcelona

My name is Raphael, I'm 22 years old and I'm a French student in my last year of a master's degree in business school. I will be in Barcelona to do an internship for 6 months in a start-up. I am looking for a flat share for 6 months from January 2022.I am rather discreet at the beginning but very sociable once the introductions are made, I love going out, doing sports, partying and going to bars.I am also very tidy, respectful and organised. I have also lived in a flat share in Buenos Aires for two months, so I know what it is like to live with other people.As for my criteria, I am not very complicated, I just want a room with a double bed !
